APPENDIX B
TROUBLESHOOTING CONTINUED
•
UNSUPPORTED FILE SYSTEM
o The PICS firmware update program was unable to locate a volume on the USB Flash drive
formatted with either of the two supported file systems, FAT(16) or FAT32.
o On USB Flash drives containing multiple partitions, only the first primary partition is examined.
•
UNSUPPORTED VOL SECTR SIZE
o The ‘Bytes Per Sector’ parameter of the detected FAT volume is not equal to the value, 512 bytes,
supported by the PICS firmware update program.
o This is an uncommon error that should only occur when using a non-standard USB Flash drive.
•
VOLUME MAY BE CORRUPTED
o Information gathered from the FAT volume indicates that it may be corrupted.
o This can result from either: (A) not dismounting the volume properly, e.g., pulling the USB Flash
drive out of a USB port without first using the “Safely Remove…” feature, or (B) the occurrence of a
disk read/write error, indicating that some of the USB Flash drive’s memory sectors may have gone
bad.
•
UPDATE FILE NOT FOUND
o The PICS firmware update program was unable to locate a filename that matches the firmware
update file, MPupdate.cfw, in the volume’s “root” directory.
o Check the filename of the firmware update file on the USB Flash drive to make sure it is named
properly, including its three-letter extension. The filename is not case-sensitive.
o Check the location of the firmware update file on the USB Flash drive to make sure it is located in
the “root”, i.e., not inside of any folder.
•
UPDATE FILE IS CORRUPTED
o The firmware update file that was found has failed one of the PICS firmware update program’s
integrity checks, meaning it contains invalid data that cannot be used.
o Try re-loading the firmware update file onto the USB Flash drive.
o Try obtaining a fresh copy of the firmware update file, either by re-downloading the original file you
received or by requesting a new copy from CUES Customer Service.
•
ERROR DURING PROGRAMMING
o Some of the raw firmware data being programmed into memory failed the verification step, i.e., the
data read back differed from the data that was written.
o This can result from a problem with the microcontroller on the main circuit board inside the PICS
Control Unit.
